<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>字体属性</title> <style> div{ border:1px solid red; width:100px; /* 浮动起来,可以位于第一行 */ } .div1{ width:100px; height:100px; /*margin-left: 50px;*/ /*margin-top:50px;*/ } .div2{ width:200px; height:200px; /*设置内边距*/ padding:50px; /*这样的话,外部盒子会变大 解决方案:设置盒子的属性,让width和height就是盒子最终的大小 */ box-sizing:border-box; } .div3{ float:left; } .div4{ float:left; } .div5{ float:right; } </style> </head> <body> <div class="div2"> <!--里面的盒子为主体,居中显示则需要设置外边距--> <div class="div1"> </div> </div> <div class="div3">aaaaa</div> <div class="div4">bbbbb</div> <div class="div5">ccccc</div> </body> </html>
三、案例:使用CSS美化注册页面
